Small Block Gearbox mount

Hello,

I need to replace the rubber insert on the n/s gearbox mount on my 83 driver, the one on the top of the box. Part number 171199214. it is nla at vw and I have ordered the equivalent from gsf but it has turned up with  diameter of 64 mm, 4mm to big.

Their part number is 171199214h which is meant to fit but it obviously doesn?t.

Any help on where I can get the correct size rubber?

NEED HELP PRONTO CAR OFF THE ROAD!!!!

They are not available anymore. I have a couple of spare mounts if you need one.
